    Journal PapersTransportation research part F: traffic psychology and behaviour , Volume 76 , 2021 January 1, {Pages 167-177 }

    Abstract

    The passing manoeuvre requires a driver to make decisions and take actions which are dependent on his/her behavioural characteristics and driving ability. However, previous works on passing rate models have exclusively considered geometric and traffic-related variables. This study aims at bridging this gap by investigating the influence of driver profile (i.e., age, gender, nationality - Italian or Iranian - aggressive driving scores, driving exposure) on passing frequency. A driving simulation experiment involving 54 drivers (36 Italians, 18 Iranians) was conducted along a 6.67?km segment of a two-lane rural highway with passing manoeuvres permitted along 25% of its length. Controlled factors included traffic flow and speed in the oncoming

    Journal PapersAccident Analysis & Prevention , Volume 139 , 2020 May 1, {Pages 105487 }

    Abstract

    A passing maneuver allows drivers to maintain their desired speed on two-lane highways. However, it entails a high risk of collision with vehicles travelling in the opposite direction. Investigating drivers’ behavior while performing passing maneuvers could provide helpful information on the factors that influence this process. Driving simulators have become important tools for driving behavior research studies as they are safe, facilitate the controlled use of experimental variables, and generate detailed output data. It remains to be seen whether simulator results can be considered representative of real-life driving conditions. With respect to passing maneuvers, no study has made a comprehensive and direct comparison between drivers’

    Journal PapersJournal of transportation engineering, Part A: Systems , Volume 146 , Issue 10, 2020 October 1, {Pages 04020117 }

    Abstract

    The passing zone (PZ) is that part of two-lane highways in which drivers can safely overtake slower vehicles. Several studies have presented passing rate models in the PZ. However, there is no model to predict the passing rate in PZs shorter than 350?m. Furthermore, the effect of variables such as lane width and the proportion of motorcycles on the passing rate were not investigated in previous works. This study assessed the effects of these variables on the passing rate and presents a prediction passing model for short PZs. Data were collected from seven PZs using a drone on three different two-lane rural highway segments in Iran. The results showed that the passing rate depends on the lane width, the absolute vertical grade, the flow rate

    Abstract

    Intersections are one of the elements that play an important role in urban networks. Analysis of drivers’ performance at unsignalised intersections is crucial, especially in left-turning movements due to their several inherent conflicts and variety of drivers’ maneuver types which affect traffic safety and capacity at such intersections, so the purpose of this paper is to introduce how the behaviour of drivers will be specified in left-turning at unsignalized intersection. For this study, traffic data were collected using a fixed digital camera. First, the vehicle speed profiles are categorized into descending-ascending slope (type (A)), the smooth descending-ascending slope (type (B)) and ascending slope (type (C)).The effects of the i

    Abstract

    Road safety has recently been considered an important issue in the country. Single-vehicle accident statistics show the importance of this issue. From a safety viewpoint, drivers need to have a reasonable time window for hazard recognition and reaction; therefore, the hazard has to be in sight from a distance preferably longer than the standard minimum stopping sight distance. Nevertheless, if the roadside configuration makes the sight available for a very long distance, the hazard properties are the ones defining the visibility. The hazard size, color, and mobility are some of the most important hazard properties, which may mainly interact with ambient light (like being day or night) and driving speed. In this research, effect of hazard pr

    Abstract

    Passing zones afford sufficient passing distance for passing vehicles on two-lane rural highways. This study aimed to assess the effects of geometric and traffic variables on the safety of short passing zones using the rate of passing maneuvers ending in the no-passing zone as a surrogate safety measure. A Poisson regression model was applied to aerial data collected by drone at seven passing zones. The findings showed that increase in the length of the passing zone corresponds to decrease in the rate of passing maneuvers ending in the no-passing zone. The passing rate is also affected by the lane width, the percentage of heavy vehicles in the subject direction, and the directional split in the subject direction. The rate of passing maneuve

    Abstract

    Paying attention to the effective causes of pedestrian safety is one of the components of urban transportation. Non-signalized intersections are considered a place with having high levels of risk because of happening many different conflict situations between vehicles and pedestrians. In this paper, the variables which are influential on the pedestrian safety based on the Post Encroachment Time are assessed. Such an assessing is done by linear regression models. For this purpose, the data was extracted observing a non-signalized intersection in Tehran called Vesal Shirazi-Bozorgmehr. The results demonstrate that the variables such as the vehicle, being a taxi and the pedestrians having unusual stops are effective in PET, having coefficients

    Abstract

    Transportation safety is the most important criterion in the engineering design of roads. Rural roads pedestrian accidents statistics show that this type of accident is tremendously important. From the safety point of view drivers need to have a reasonable time window for hazard recognition, reaction initiation and execution. This means that the hazard has to be in sight from a distance longer than the minimum stopping sight distance. Nevertheless, if the road side configuration make the sight available for a very long distance, it’s the hazards characteristics which defines the visibility along with the drivers’ behavioral characteristics as a human. The hazard color and mobility are some of the most important hazard characteristics. I

    Abstract

    In many accidents, if the driver responds on time, those will not occur or theirs’s severity is low. One of the main steps before responding is to detect the hazard. Various variables affect drivers' hazard detection and perception, most of which are driver characteristics. In this research, it was assumed that driver characteristics, such as demographic characteristics, lifestyle features and cognitive characteristics, have an impact on driver hazard perception. In this regard, a driving simulator was used and different hazard scenarios of rural road were developed. Finally, a quantitative index and optimal structural equation model were proposed to determine the relationship between hazard perception and driver characteristics. The resu

    Abstract

    Analyzing the pedestrian safety without using the accident data has become common in the recent years. Investigating the pedestrian safety based on the conflict idea is becoming popular. Therefore, this paper has investigated variables that cause interaction between vehicles and pedestrians for pedestrians, to be potentially dangerous and possibly critical situation. Two measures were used in this study: Time to Collision (TTC) and Post-Encroachment Time (PET). First, an unsignalized intersection was chosen to launch this study. The site was filmed by camera for about 8 hours in two days. The different steps of this study were: identifying the conflict situations, tracking pedestrian and vehicles and then obtaining the PET, TTC, and the oth

    Abstract

    One of the most important parts of the driver reaction is detecting hazard in prominent time. A hazard is detected in the right time if it is completely visible for the driver. There are various hazard types such as fixed obstacles، pedestrians، and animals that some of them cross the road. Right-time hazard detection and the post-reaction is of high importance in accident prevention. It is assumed، in this paper، that increasing crossing speed of hazards affects the driver's hazard detection. Different driver types including novice، low-experienced، and experienced drivers are chosen and various environmental scenarios are also designed. The eventual suggested model is Fuzzy Sugeno that estimates relation between the driver's detecti

    Abstract

    Pedestrians are subjected to high levels of risk at non-signalized intersections. Pedestrians at these intersections have conflicts with different types of vehicles such as motorcycles and cars. In this paper, pedestrian safety is compared between those two groups of vehicles using Time to Collision (TTC) as well as the Post Encroachment Time (PET). Data were collected from an intersection called Vesal-Bozorgmehr in Tehran. The one-way ANOVA was used to compare those two groups. The number of observations for each TTC and PET being the dependent variable was 758 and 791 respectively. Analyses indicated that LogTTC in conflicts between vehicles and pedestrians is 0. 03 units more than conflicts between motorcycles and pedestrians and LogPET

    Journal Papers , Volume 16 , Issue 36000860, 2019 January 1, {Pages 33-46 }

    Abstract

    The level of safety of transportation being low often considers an obstacle to sustainable development. Pedestrian safety is one of the essential problems, researchers of the safety of transportation face. Since non-signalized intersections lack the controllers of safety and have many conflicts between pedestrians and vehicles, are considered to be a dangerous place for pedestrians. The conflict between pedestrians and motorcycles and the variables which influence those conflicts are the issues that are not paid enough attention by researchers. The data used in this paper have been achieved using the image processing method. The effects of the variables related to the pedestrians and the motorcycles on Time to Collision (TTC) have been esti

    Abstract

    The low level of safety of transportation causes expanding social and economic consequences. It's also an obstacle to sustainable development. The pedestrian safety is one of the most important issues in the safety of transportation. Non-signalized intersections are one of the places in which there is too much risk for pedestrians because there are rarely any control equipment for pedestrians and vehicles movements. Therefore many conflicts between these two parties occur at such a place. Many effective variables on the intensity of conflicts have been identified، but many of them have been analyzed in signalized intersections and special types of movements like left-turn or right-turn. In this research، the effects of the type of movemen

    Abstract

    Objective: Considering the high annual number of fatal driving accidents in Iran, any approach for reducing the number or severity of driving accidents is a positive step toward decreasing accident-related losses. Accidents can often be avoided by a timely reaction of the driver. One of the steps before reacting to a hazard is perception. Some driver characteristics may affect road hazard perception. In this research, it was assumed that various driver characteristics, including demographic characteristics and cognitive characteristics, have an impact on driver perception.Methods: The driving simulator used in this research provides various scenarios; for example, passing a pedestrian or animal across the road or placing fixed objects in a

    Effect of road geometry on driver fatigue in monotonous environments: A simulator study

    Behzad Farahmand, Amin Mirza Boroujerdian
    Journal PapersTransportation research part F: traffic psychology and behaviour , Volume 58 , 2018 October 1, {Pages 640-651 }

    Abstract

    Driver fatigue, induced by task monotony can increase the risk of road accidents. Highways are usually designed with few geometric changes so that high-speed traveling would be possible. Such conditions when combined with repetitive and stimulus-free environments, create a monotonous driving experience that can lead to mind wandering and task disengagement, and subsequently affect driver’s performance. This paper focuses on the relationship between road geometry and driver’s vigilance level in monotonous environments. Therefore a driving simulator experiment with three different scenarios, which were originated from three existing highways in rural areas of Iran, with low, moderate, and high levels of geometric variety was developed.

    Journal PapersInternational Journal of Transportation Engineering , Volume 6 , Issue 2, 2018 October 1, {Pages 145-156 }

    Abstract

    Accurate estimation of saturation flow rate is a prerequisite for accurate estimation of level of service and delays of signalized intersections. Saturation flow rate of intersections depends on many factors, including traffic behavior and culture. One of the important problems of traffic behavior in Iran is the violation of law at the physical region of intersections. The main purpose of this paper is to study the effects of violations such as pedestrians and motorcyclists ignoring the red light and vehicles changing their lanes at the physical region of intersections on the saturation flow rate.
